This article focuses upon the developing professionalism and emergent thinking of 36 secondary trainee teachers, in terms of their motivation to teach, their early beliefs about teaching and the teaching-learning process and their views of themselves as trainee teachers. It analyses their perspectives on how they expect to learn to become teachers and how these perspectives match with their early experiences on their training courses. Discussion of these starting points of beginning teachers reveals some understanding of models of outstanding classroom practice, but equally a relatively unsophisticated analysis of the essential characteristics of this practice. The challenge for teacher educators is to frame courses in such a way that beginning teachers are provided with the contexts and the methodologies whereby they can reflect upon their own preconceptions and refine their own understandings as to how they themselves learn as teachers, to enable them to facilitate the learning of pupils and to fulfil their own clearly articulated aspirations to become quality teachers.
